ALEXANDER ANDERSON SCOTT, OF KNOXVILLE, TENNESSEE.

DRYING-HOUSE.

SPECIFICATION forming part of Letters Patent No. 759,135, dated May 3,1904.

Application filed April 2, 1903. Serial No. 150,786. (N0 model.)

To (ZZZ whom it may concern:

Be it known that I, ALEXANDER ANDERsoN SCOTT, a citizen of the UnitedStates, residing at Knoxville, in the county of Knox and State ofTennessee, have invented certain new and useful Improvements inDryingHouses, of which the following is a specification.

My invention relates to houses or sheds for drying brick and otherproducts by artificial heat, and has for its object to provide astructure consisting of a number of parallel and independentcompartments or tunnels with means for evenly distributing the cold airto the various compartments, heating it and dis tributing the airthrough each individual tunnel, and after passing through the dryingproducts removing it to make room for freshlyheated air. This Iaccomplish by means of the structure hereinafter described, andillustrated in the drawings, in which Figure 1 is a view in verticalsection of my drying-shed; Fig. 2, a fragmental ground plan view showingthe arrangement of cold-air ducts; Fig. 3, a side view of the shed,showing the outer ends of the cold-air ducts and the valves forcontrolling the flow of air therethrough; Fig. 4, a detail View of thetop of one of the tunnels, showing the arrangement of dampers; and Fig.5, a fragmental view showing the steam-conduit and the means fordistributing the steam to the tunnels.

Referring to the drawings, in which similar reference charactersindicate corresponding parts throughout the several views, A representsa number of supports or rests, made of masonry or other suitablematerial, erected on suitable foundations and having their tops providedwith strips of boards B to act as racks to receive the articles to bedried. The two outer supports or rests are extended upward to form theside walls C of the shed, while the intermediate supports havepartitions D erected thereon. E represents the ceiling resting on saidpartitions D and secured in side walls C.

F represents a series of openings in ceiling E over each tunnel orcompartmentG formed by rests A and partitions D.

H represents the roof, spaced apart from the ceiling E to form a passageto a stack or stacks I, erected on said roof. The ends of said shed areclosed by suitable walls having doors (not shown) admitting to eachtunnel.

J represents beams, made of steel or other suitable material, erectedinto rests A and above the level of the ground. K represents railssecured to said beams, over which trucks carrying the articles to bedried are conveyed to the supports or rests A, or the trucks may beallowed to stand on said rails during the drying process,ifdesired.Lrepresentssteampipes laid on said beams J between and outside of saidrails K to heat the air conveyed from the outside to said tunnels bymeans of ducts M. There is an equal number of said ducts M for eachtunnel, the pipes extending from the outside walls to the respectivetunnels and having upwardly-turned ends we to deliver the air to thespace under beams J, from whence it passes over steam-pipes L, where itis heated, and then through the drying articles upward and throughopenings F to the passages between ceiling E and roof H Y to the stackI. In narrow tunnels it may be found desirable or necessary to omit thepipes at the side of the rails, which maybe done without departing fromthe spirit of my invention.

N represents damper plates pivotally mounted on ceiling E and operatedby slidable rods 0, connected with said plates by means of Wires 0. Itis obvious that said rods should extend outside the walls of the tunnelto permit of operating them.

1 represents valves slidably mounted over the outer openings of ducts Mto regulate the amount of air passing through said ducts to thedrying-tunnels.

Each set of steam-pipes L is connected with a header Q, which is tappedinto a steam-conduit R, connected with a boiler. (Not shown.) Byproviding a valve S in each header the heat in each tunnel may beregulated to suit the products being treated or can be cut off entirelywhen it is desired toremove the dried products and introduce new ones.

Having thus described my invention, what I claim is- 1. In adrying-house, a multiplicity of parallel tunnels, separate cold-airduets extending inwardly from the sides of the house to the tunnels, theends of said ducts inside of the tunnels turned up, said ducts being thesame length for each tunnel and arranged alternately with the ductsleading to the other tunnels so that the air is evenly distributed amongthe several tunnels and throughout each tunnel separately, and means toheat the air, substantially as shown and described.

2. In a drying-house, a multiplicity of parallel tunnels, a series ofcold-air ducts extending inwardly from the sides of the house to theseparate tunnels at equal distances apart, the ends of said ducts insideof the tunnels turned up, a steam-conduit arranged along the ends of thetunnels, a header tapped into said conduit opposite each tunnel, andsteam-pipes tapped into said headers and running lengthwise of thetunnels above the opening to said cold-air ducts, substantially as shownand described.

3. In a drying-house, tunnels formed by upright rests, partitionserected on said rests and a ceiling supported by said partitions,horizontal beams built into said rests, tracks supported by said beams,a series of cold-air ducts leading from the outside of the house toeachseparate tunnel at equal distances apart, the ends of said ductsinside of the tunnel turned up, a steam-conduit arranged along the endsof the tunnels, a header tapped into said conduit opposite each tunnel,and steampipes tapped into each header and supported by said beams,substantially as shown and described.

4. In a drying-house, tunnels formed by upright rests, partitionserected on said rests and a ceiling supported by said partitions andhaving openings therein, a roof above said ceiling and spaced aparttherefrom, a stack rising from said roof, beams built into said rests,tracks secured to said beams, a steamconduit, headers tapped into saidconduit opposite to each tunnel, a number of pipes tapped into eachheader, and extending through the tunnel, and separate cold-air ductsextending from the sides of the house inwardly to the tunnels,substantially as shown and described.

5. In a drying-house, tunnels formed by upright rests, partitionserected on said rests and a ceiling supported by said partitions andhaving openings therein, a roof above said ceiling and spaced aparttherefrom, a stack rising from said roof, beams built into said rests,tracks secured to said beams, a steamconduit, headers tapped into saidconduit opposite to each tunnel, anumber of pipes tapped into eachheader, and extending through the tunnel, and cold-air ducts extendingcrosswise of the space below the tracks, said ducts being arranged sothat an equal number open into each tunnel and at equal distances fromone another, substantially as shown and described.

In testimony whereof I hereto affix my signature in the presence of twowitnesses.
